WUFI Pro Logo



This manual describes the installation, shows the first steps with the software and gives an overview about the features of WUFI®.

Using a building envelope as an example, it is shown how to create a construction, how to set boundary, surface transfer and initial conditions and finally how to calculate and assess this example.

Guideline for the calculation of extensive green roofs

The “Guideline for the calculation of extensive green roofs” and the requisite material data sets have been developed to allow reliable WUFI® simulations and planning of green coverings, in particular on wood constructions.
These investigations were performed as part of the project

“Ermittlung von Materialeigenschaften und effektiven Übergangsparametern von Dachbegrünungen
zur zuverlässigen Simulation der hygrothermischen Verhältnisse in und unter Gründächern
bei beliebigen Nutzungen und unterschiedlichen Standorten.”

(“Determination of material properties and effective surface transfer parameters of green roof coverings
for the reliable simulation of the hygrothermal conditions in and below green roofs for arbitrary types of use and different locations.”

funded by the Research Initiative “Future Building” of the Federal Institute for Research on Building, Urban Affairs and Spatial Development.

Guideline for the calculation of gravel roofs

The “Guideline for the calculation of gravel roofs” and the requisite material data set have been developed on the basis of simulations reproducing investigations and measurements performed on gravel roofs in Holzkirchen, Gräfelfing and Milan.

Handling of typical constructions in WUFI®

A short survey of how to treat typical constructions in WUFI®, e.g. flat roofs, exterior walls with ETICS, basement walls etc. Under ‘example cases’ you can download the project files for the cases described in the tutorial.

Guideline for modeling water-repellent treatment of a façade

Model a water-repellent treatment of a façade by adjusting the A-value.

Hygrothermal Simulation of ventilated pitched roofs with effective transfer parameters

The study at hand presents the preliminary research results from field trials in which the thermal behavior was investigated on several different ventilated roof constructions. Radiation related parameters will be provided for different roofing situations as well as a method to calculate ventilated roofs by means of hygrothermal simulation using effective surface transfer parameters.

Guideline for assessing condensation problems in hydrophobic mineral fiber

This guideline describes the procedure to evaluate the condensation risk within a hydrophobic mineral fiber.

Guideline for Using the Air Infiltration Source in WUFI®

This guideline describes when to consider an infiltration source in the simulation and how to apply it in WUFI®.

You can find additional information in the Online Help of WUFI® Pro.

WUFI 2D Logo



This manual describes the installation of WUFI® 2D, guides the user through the first steps with the program and provides a short overview of its capabilities.

Calculation Example

This introduction will show you how to model a building component in WUFI® 2D, how to specify boundary, surface transfer and initial conditions, how to perform the calculation and how to analyse the results.

As an example illustrating each step, we will analyse the hygrothermal behavior of a concrete ceiling supported by a brick wall with exterior insulation.

Online Help

The current version of WUFI® 2D’s online help is separately available for download.
Currently it is identical with the online help included in the installation package of WUFI® 2D version 3.2.

Computational parameters

Discussion of the numerical settings in WUFI® 2D.

How to add sources and sinks in WUFI® 2D.
Determination of source strength

How WUFI® 2D determines the source strengths of heat or moisture sources when these are controlled by the boundary conditions.

How to import a DFX file in WUFI® 2D

You can find additional information in the Online Help of WUFI® 2D.

ORNL weather files

This Add-On Installation provides additional weather files for more than 100 locations in North America (only for WUFI Pro 5.3 – DB24.72 or higher; not needed for WUFI Pro 6.x, here the data are already included). Data source is ASHRAE Research Project 1325. Adaption for WUFI® conducted by Oak Ridge National Laboratory, sponsored by the U.S. Department of Energy.

The download contains 3 severe years each for Albany NY, Albuquerque NM, Amarillo TX, Anchorage AK, Asheville NC, Astoria OR, Atlanta GA, Atlantic City NJ, Austin TX, Baltimore ND, Billings MT, Birmingham AL, Bismarck ND, Boise ID, Boston MA, Boulder CO, Brownsville TX, Buffalo NY, Burlington VT, Casper WY, Charleston SC, Charlotte NC, Chicago IL, Cleveland OH, Colorado Springs CO, Columbus OH, Concord NH, Dayton OH, Daytona Beach FL, Des Moines IA, Detroit MI, El Paso TX, Elko NV, Eugene OR, Fairbanks AK, Fargo ND, Flagstaff AZ, Fort Wayne IN, Fort Worth TX, Fresno CA, Grand Island NE, Grand Rapids MI, Green Bay WI, Hartford CT, Houston TX, Huntington WV, Indianapolis IN, International Falls MN, Jackson MS, Jacksonville FL, Kansas City MO, Key West FL, Knoxville TN, Las Vegas NV, Lexington KY, Little Rock AR, Los Angeles CA, Louisville KY, Macon GA, Madison WI, Memphis TN, Miami FL, Minneapolis MN, Mobile AL, Nashville TN, New York City NY, Norfolk VA, Oklahoma City OK, Omaha NE, Philadelphia PA, Phoenix AZ, Pittsburgh PA, Port Arthur TX, Portland OR, Providence RI, Raleigh NC, Rapid City SD, Reno NV, Roanoke VA, Sacramento CA, Salt Lake City UT, San Antonio TX, San Diego CA, San Francisco CA, Savannah GA, Seattle WA, Sheridan WY, Spokane WA, Springfield MO, St. Louis MO, Syracuse NY, Tampa FL, Tucson AZ, Tulsa OK, Victoria TX, Wichita KS, Wilmington DE, Yakima WA; Calgary, Ottawa, Quebec, St. John’s, Toronto, Winnipeg, Vancouver.

Weather file list for Google Earth

This *.KMZ file displays the locations of the weather files registered in WUFI’s database by feeding them to Google Earth (which you must have installed).
Some of these weather files are included with WUFI; the others must be purchased from the respective vendor, but they can then immediately be used for WUFI® calculations, without further configuration.

A click on one of the WUFI® icons will display some information about the respective weather file.

Weather data Holzkirchen 1991

The 1991 weather data measured in Holzkirchen can be considered representative for Holzkirchen climate conditions. They are included in the WUFI® installation packages, but IBP also offers them separately for general purposes.

Material files

Guideline for the import of material data in xml format into WUFI®

User defined material datasets can be exported and imported in WUFI® as an xml file. The following guideline explains how these xml files can be used in WUFI®.

Material characteristics: Companies' products

In addition to the generic materials like “plasterboard” or “hardwoods”, there are also companies´ products implemented in the material data base of WUFI®, listed by their manufacturer-specific product description.

The list below contains products, for which characteristics have been determined and which are included in the latest material data base release. For those products which will be implemented in the upcoming data base version, you can find characteristics as xml-file for download and import in WUFI®.

You can display the version number of your data base by choosing the menu item “? → About WUFI“.
